Walker’s forensic experts perform thorough site investigations, critical reviews, and advanced analyses to solve a wide variety of problems. Our broad spectrum of forensic services ranges from structural engineering to architecture and building envelope.

Whether a simple failure of a distinct system or a complex, interconnected problem, we can precisely identify the root cause or factors resulting in failure. Our education, training and experience in design, forensic skills, analysis and visualization allows us to succinctly and effectively communicate our findings.

Our experts stay up-to-date and contribute to the field by participating in professional committees, writing and updating codes, and publishing peer-reviewed technical articles.

Our large geographic presence with offices throughout the United States allows us to efficiently respond to local needs with specific knowledge from expert designers and practitioners.

Forensic Investigations and Assessments

Design Errors and Omissions

Our thorough investigations establish causes of failures and defects. To investigate design errors and omissions, Walker’s forensic experts rely upon their knowledge and experience designing structures and their components as well as collaborating with our structural and architectural design professionals around the company.

Construction Defects

Walker Consultants can help you understand why and how things went wrong in a structure, whether during construction or after completion. Our subject-matter experts perform meticulous site investigations to document and identify defects. Then, we review design documents, specifications, applicable codes and standards to establish cause(s) of failures and defects.

Diagnostic Testing

Destructive and Non-Destructive

Walker has in-house diagnostic testing capabilities to verify sources of distress or structural integrity within a structure and facilitate a greater understanding of the structural system behavior under simulated conditions. Walker also provides short- to long-term behavior monitoring to ascertain ongoing problems. Diagnostic testing capabilities include:

  • Load testing to verify structural integrity
  • Air and water infiltrations testing of exterior wall elements
  • Crack width monitoring
  • Water testing for leakage at building components (plazas, roofs, expansion joints, etc.)
  • Measurements of structural movements and/or settlement

Water Damage

Our experts identify water damage that can cause harm in the short and long-term life of a structure. Water can infiltrate all aspects of a building enclosure from various sources and cause untold damage until identified. Walker investigates structures to reveal underlying conditions that can lead to further damage if left un-repaired. During assessments and investigations, our experts perform visual observations, testing consulting, and document the extent of damage.

Risk Analysis

Walker offers risk analysis services for every building type and occupancy. Risk can be thought of as a combination of exposure and vulnerability. Walker engineers use the most up-to-date hazard models and data to assess the exposure of a given building, based on its location and structural properties. The services we provide include probable maximum loss (PML) studies for natural and man-made hazards and life-cycle cost analysis for anticipating structural deterioration. In addition to quantifying risk, we help clients understand exposure, vulnerability, and the resulting risk as it applies to individual buildings and portfolios, so that they can make critical risk management decisions with the information.

Litigation Services

Walker provides attorneys, insurance companies, adjusters, building owners, and design firms with a wide range of litigation support. Our technical experts are skilled at providing testimony and litigation support in a variety of formats using the most effective tools.
